Drum type washing machine
Document Type and Number:
Japanese Patent JP5940206
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a drum-type washing machine excellent in tub washing.SOLUTION: Between a rinsing step and a dewatering step, a predetermined amount of washing water is supplied into an outer tub (S301 and S302), and then an inner tub is rotated in a clockwise direction at a predetermined rotation speed (S303) while a solenoid valve for supplying water for tub cleaning is opened. After a predetermined period of time has passed (S304), the inner tub is rotated in a counter-clockwise direction at a predetermined rotation speed (S305). After a predetermined period of time has passed (S306), the solenoid valve for supplying water for tub cleaning is closed while the rotation of the inner tub is maintained (S307), and thus the step shifts into a dewatering step. In the dewatering step, while the rotation of the inner tub is maintained, a drain valve is opened and the washing water is discharged and a rotation speed of the inner tub is increased to a rotation speed corresponding to dewatering.SELECTED DRAWING: Figure 15
